TECHNICAL FIELD

The present disclosure relates to the terminal field, and in particular, to a side menu displaying method and apparatus, and a terminal.

BACKGROUND

Touchscreens are usually adopted on screens of terminals such as a mobile phone, a tablet computer, and an eBook reader. To prevent a user from performing a misoperation on a touchscreen, a screen locking function is usually set on a terminal in a standby process, and an operation can be properly performed on the touchscreen only after the terminal is unlocked.

In a screen locking state, to make it convenient for the user to view a new message or perform a shortcut setting, the terminal usually provides a notification bar that is triggered and displayed by a downward sliding operation. A method for displaying the notification bar is: A terminal receives a sliding operation of sliding from the top of a screen downwards, which is triggered by a user; the terminal detects whether a sliding speed of the sliding operation exceeds a preset threshold; and if a detection result is that the sliding speed exceeds the preset threshold, that is, the sliding operation is a quick downward sliding operation, the terminal moves the notification bar from the top of the screen to the screen for displaying. Then, the user may view a new message or perform a shortcut setting on the notification bar, for example, quickly enabling/disabling BLUETOOTH, quickly enabling/disabling a wireless network, and adjusting brightness of the screen.

The inventor finds that the foregoing technology at least has the following problems: When a user places a terminal in a pocket, the terminal is likely to cause friction with a finger or skin of the user, and the friction is recognized by the terminal as a quick downward sliding operation. This causes triggering and displaying of the notification bar unknown to the user, and thereby causing a misoperation to occur.

DESCRIPTION OF EMBODIMENTS

To make the objectives, technical solutions, and advantages of the present disclosure clearer, the following further describes embodiments of the present disclosure in detail with reference to the accompanying drawings.

In the embodiments of the present disclosure, a terminal may be a mobile phone, a tablet computer, an eBook reader, a Moving Picture Experts Group audio layer-3 (MP3) player, a Moving Picture Experts Group audio layer-4 (MP4) player, and the like.

FIG. 1 shows a method flowchart of a side menu displaying method according to an embodiment of the present disclosure. The side menu displaying method is applied to a terminal. The side menu displaying method includes the following steps:

Step 102: Receive a sliding operation of sliding starting from a side of a screen.

The terminal receives the sliding operation of sliding starting from the side of the screen. The side of the screen refers to an edge of the screen of the terminal. Using a rectangle screen as an example, the side of the screen may be any one of four sides of the rectangle screen.

Step 104: Detect whether the sliding operation meets a predefined condition, where the predefined condition includes that a sliding speed of the sliding operation is greater than a preset threshold, and an end position of the sliding operation is not within a preset false touch area.

The terminal detects whether the sliding operation meets the predefined condition. The terminal detects whether the sliding speed of the sliding operation is greater than the preset threshold, that is, detects whether the sliding operation is a quick sliding operation. In addition, the false touch area refers to an area in which a side menu is likely to be triggered and displayed unknown to a user. The false touch area may be a preset area with a fixed scope and may also be an area with a scope that is dynamically adjusted by recording a user operation. The side menu may include a notification bar or menu bar that is displayed by pulling down, and may further include a notification bar or menu bar that is displayed by pulling left or right, and a notification bar or menu bar that is displayed by pulling up.

Step 106: Display a side menu corresponding to the side of the screen if a detection result is that the sliding operation meets the predefined condition.

If the detection result is that the sliding operation meets the predefined condition, the terminal displays the side menu corresponding to the side of the screen. When a detection result is that the sliding speed of the sliding operation is greater than the preset threshold, and the end position of the sliding operation is not within the preset false touch area, the terminal displays the side menu corresponding to the side of the screen

In conclusion, in the side menu displaying method provided in the embodiment, a sliding operation of sliding starting from a side of a screen is received, whether the sliding operation meets a predefined condition is detected, and a side menu corresponding to the side of the screen is displayed when a detection result is that the sliding operation meets the predefined condition. The predefined condition includes that a sliding speed of the sliding operation is greater than a preset threshold, and an end position of the sliding operation is not within a preset false touch area. This resolves the problem, existing in the other approaches, that a misoperation occurs because a notification bar is triggered and displayed unknown to a user, and achieves an effect that a side menu is triggered and displayed only when a sliding operation is a quick sliding operation and an end position of the sliding operation is not within a false touch area, thereby preventing a misoperation that occurs because the side menu is triggered and displayed unknown to a user.

As introduced in the embodiment shown in FIG. 1, the false touch area may be a preset area with a fixed scope and may also be an area with a scope that is dynamically adjusted by recording a user operation. The following introduces and describes the foregoing two cases in detail in embodiments shown in FIG. 2A and FIG. 3A. First, in the embodiment shown in FIG. 2A, a false touch area is a preset area with a fixed scope.

FIG. 2A shows a method flowchart of a side menu displaying method according to another embodiment of the present disclosure. The side menu displaying method is applied to a terminal. The side menu displaying method includes the following steps:

Step 201: Preset a false touch area.

The false touch area is preset on the terminal. In this embodiment, the false touch area is a preset area with a fixed scope. With reference to FIG. 2B, the false touch area includes an area enclosed by a side 21 of the screen, two sides adjacent to the side 21 of the screen, and a first virtual side 22 parallel with the side 21 of the screen.

The side 21 of the screen refers to an edge of the screen of the terminal. Using a rectangle screen as an example, the side 21 of the screen may be any one of four sides of the rectangle screen. In this embodiment, a top side of the rectangle screen shown in FIG. 2B is used as an example of the side 21 of the screen.

Step 202: Receive a sliding operation of sliding starting from a side of a screen.

The terminal receives the sliding operation of sliding starting from the side 21 of the screen.

Step 203: Detect whether an end position of the sliding operation is within a direct display area.

The terminal detects whether an end position S of the sliding operation is within the direct display area. With reference to FIG. 2B, the direct display area and the false touch area do not mutually overlap. The direct display area includes an area enclosed by an opposite side 23 of the side 21 of the screen, two sides adjacent to the side 21 of the screen, and a second virtual side 24 parallel with the side 21 of the screen.

The terminal detects whether a vertical distance a between the end position S of the sliding operation and the side 21 of the screen is greater than a direct display threshold L₁, where the direct display threshold L₁ is a distance between the side 21 of the screen and the second virtual side 24. The terminal may set up a coordinate system on the screen in advance. The terminal first acquires coordinates of the end position S of the sliding operation, then obtains the vertical distance a between the end position S and the side 21 of the screen according to the coordinates of the end position S, and finally, compares the vertical distance a with the direct display threshold L₁.

A value of the direct display threshold L₁ is related to a length of a side adjacent to the side 21 of the screen. Generally, the direct display threshold L₁ is set to half of the length of the side adjacent to the side 21 of the screen. As shown in FIG. 2B, in this embodiment, it is assumed that the direct display threshold L₁ is half of a length H of the screen.

If a detection result is that the end position S is within the direct display area, the terminal directly displays a side menu corresponding to the side 21 of the screen. The side menu may include a notification bar or menu bar that is displayed by pulling down, and may further include a notification bar or menu bar that is displayed by pulling left or right, and a notification bar or menu bar that is displayed by pulling up. In this embodiment, it is assumed that the side menu is a notification bar that is displayed by pulling down. With reference to FIG. 2B, an area below the line of the second virtual side 24, that is, the direct display area, is considered as an area in which a user intents to perform an operation. When the sliding operation starts from the side 21 of the screen downwards and stops below the line of the second virtual side 24, the terminal considers that the sliding operation is an intentional user operation. In this case, regardless of a sliding speed of the sliding operation, the terminal displays the side menu.

If a detection result is that the end position S is not within the direct display area, step 204 is performed.

Step 204: Detect whether the sliding operation meets a predefined condition if a detection result is that the end position is not within the direct display area.

If the detection result is that the end position is not within the direct display area, the terminal detects whether the sliding operation meets the predefined condition. The predefined condition includes that the sliding speed of the sliding operation is greater than a preset threshold, and the end position of the sliding operation is not within the preset false touch area.

The step includes the following two substeps:

First, detect whether a vertical distance between the end position of the sliding operation and the side of the screen is greater than a false touch threshold.

The terminal detects whether the vertical distance a between the end position S of the sliding operation and the side 21 of the screen is greater than a false touch threshold L₂, where the false touch threshold L₂ is a distance between the side 21 of the screen and the second virtual side 22. A value of the false touch threshold L₂ is also related to a length of a side adjacent to the side 21 of the screen, and the false touch threshold L₂ is less than the direct display threshold L₁. Generally, the false touch threshold L₂ is set to approximately one third of the length of the side adjacent to the side 21 of the screen. As shown in FIG. 2B, in this embodiment, it is assumed that the false touch threshold L₂ is one third of the length H of the screen.

When the sliding operation starts from the side 21 of the screen downwards and stops before the sliding reaches below the line of the second virtual side 24, the terminal considers that the sliding operation may be an unintentional user operation. In this case, the terminal detects whether the vertical distance a between the end position S of the sliding operation and the side 21 of the screen is greater than the false touch threshold L₂, that is, detects whether the end position S of the sliding operation is within the false touch area.

Second, if a detection result is that the vertical distance is greater than the false touch threshold, detect whether the sliding speed of the sliding operation is greater than the preset threshold.

When the detection result is that the vertical distance is greater than the false touch threshold L₂, the predefined condition that the end position S of the sliding operation is not within the preset false touch area is met. In this case, the terminal continues to detect whether the sliding speed of the sliding operation is greater than the preset threshold.

The sliding speed may be expressed in the number of pixels that are slid per unit time. A higher sliding speed indicates that more pixels are slid per unit time; on the contrary, a lower sliding speed indicates that less pixels are slid per unit time.

In the foregoing first and second substeps, when a detection result is that the vertical distance a between the end position S of the sliding operation and the side 21 of the screen is less than the false touch threshold L₂, or when the detection result is that the vertical distance a between the end position S of the sliding operation and the side 21 of the screen is greater than the false touch threshold L₂ but the sliding speed is less than the preset threshold, the sliding operation does not meet the predefined condition, and in this case, the terminal does not display the side menu. On the contrary, when the detection result is that the vertical distance a between the end position S of the sliding operation and the side 21 of the screen is greater than the false touch threshold L₂ and the sliding speed is greater than the preset threshold, the sliding operation meets the predefined condition, and the terminal performs step 205.

Step 205: Display a side menu corresponding to the side of the screen if a detection result is that the sliding operation meets the predefined condition.

If the detection result is that the sliding operation meets the predefined condition, the terminal displays the side menu corresponding to the side 21 of the screen. The terminal displays the side menu in the following two possible implementation manners:

In a first possible implementation manner, the terminal displays the side menu only after determining that the sliding operation meets a condition for displaying the side menu.

In a second possible implementation manner, when receiving the sliding operation of sliding starting from the side of the screen, the terminal moves the side menu along with a trigger object such as a finger of the user, and completely displays the side menu after determining that the sliding operation meets a condition for displaying the side menu, or otherwise withdraws the menu.

In conclusion, this embodiment provides two manners for triggering and displaying the side menu: first, the vertical distance a between the end position S of the sliding operation and the side 21 of the screen is greater than the direct display threshold L₁; second, the vertical distance a between the end position S of the sliding operation and the side 21 of the screen is less than the direct display threshold L₁, but is greater than the false touch threshold L₂, that is, the end position S of the sliding operation is not within the preset false touch area and the sliding speed of the sliding operation is greater than the preset threshold.

It should be noted that, before step 203, the following step may further be included. The terminal detects whether a vertical distance between a start position of the sliding operation and the side of the screen is greater than a trigger threshold, where the trigger threshold is less than the false touch threshold; if a detection result is that the vertical distance between the start position of the sliding operation and the side of the screen is less than the trigger threshold, step 203 is performed; otherwise, no operation is performed. The trigger threshold is generally set to approximately one twentieth of a length of a side adjacent to the side of the screen. Setting the trigger threshold is to determine whether the start position of the sliding operation is within a trigger area between the side of the screen and the line of the trigger threshold. It is considered that the sliding operation is a sliding operation that is used to trigger and display the side menu only when the start position of the sliding operation is within the trigger area.

It should further be noted that the problem raised in the other approaches seems more notable after a floating touch technology is applied to a terminal. Therefore, in a screen locking state, the terminal can disable a floating touch function. A user can trigger displaying of a side menu only using a sliding operation with direct contact with a screen. Further, the terminal may further collect a distance between the screen and an obstacle in front of the screen using a distance sensor or collect a light intensity value of the front of a screen using a light intensity collector to analyze and determine whether the terminal is in a user operation state. When the distance between the screen and the obstacle in front of the screen is less than a predefined distance value or when the light intensity value of the front of the screen is less than a predefined light intensity value, it is considered that the terminal is not in the user operation state, and in this case, none of sliding operations received triggers displaying of a side menu.

In conclusion, in the side menu displaying method provided in the embodiment, a sliding operation of sliding starting from a side of a screen is received, whether the sliding operation meets a predefined condition is detected, and a side menu corresponding to the side of the screen is displayed when a detection result is that the sliding operation meets the predefined condition. The predefined condition includes that a sliding speed of the sliding operation is greater than a preset threshold, and an end position of the sliding operation is not within a preset false touch area. This resolves the problem, existing in the other approaches, that a misoperation occurs because a notification bar is triggered and displayed unknown to a user, and achieves an effect that a side menu is triggered and displayed only when a sliding operation is a quick sliding operation and an end position of the sliding operation is not within a false touch area, thereby preventing a misoperation that occurs because the side menu is triggered and displayed unknown to a user.

In addition, the embodiment provides a specific manner of determining a false touch area, that is, presetting an area with a fixed scope as a false touch area. In this embodiment, presetting a false touch area produces a good effect on shielding some unintentional sliding operations of a user.

In the following embodiment shown in FIG. 3A, a false touch area is an area that is dynamically adjusted by recording a user operation.

FIG. 3A shows a method flowchart of a side menu displaying method according to still another embodiment of the present disclosure. The side menu displaying method is applied to a terminal. The side menu displaying method includes the following steps:

Step 301: Receive a sliding operation of sliding starting from a side of a screen.

The terminal receives the sliding operation of sliding starting from the side of the screen.

Step 302: Detect whether the sliding operation meets a predefined condition.

The terminal detects whether the sliding operation meets the predefined condition, where the predefined condition includes that a sliding speed of the sliding operation is greater than a preset threshold, and an end position of the sliding operation is not within a preset false touch area. With reference to the embodiment shown in FIG. 2B, in this embodiment, it is assumed that an initially set false touch area is an area of one third of a forepart of the screen, that is, an area above the line of the first virtual side 22 in the embodiment shown in FIG. 2B. As shown in FIG. 3B, an area indicated by transverse lines in the left figure is an initially set false touch area.

Step 303: Display a side menu corresponding to the side of the screen if a detection result is that the sliding operation meets the predefined condition.

If the detection result is that the sliding operation meets the predefined condition, the terminal displays the side menu corresponding to the side of the screen.

Step 304: Record, in a successful triggering sample library, the sliding operation that successfully triggers displaying of the side menu this time.

The terminal records, in the successful triggering sample library, the sliding operation that successfully triggers displaying of the side menu this time, where a sliding operation that successfully triggers displaying of the side menu each time and an end position of each sliding operation are recorded in the successful triggering sample library.

Step 305: Update a size and/or a location of a false touch area at a preset time interval according to distribution density of the end positions of the sliding operations on the screen, where the end positions are recorded in the successful triggering sample library.

The terminal updates the size and/or the location of the false touch area at the preset time interval according to distribution density of the end positions of the sliding operations on the screen, where the end positions are recorded in the successful triggering sample library. Because users have their own use habits, sliding operations, including tracks of the sliding operations, sliding distances, and end positions of the sliding operations, that the users perform on a terminal are the same or similar in most cases. The terminal may adjust the size and/or the location of the false touch area at the preset time interval according to the user habits, so that the false touch area is more precise, and probability of a misoperation is further reduced.

The step includes the following substeps:

First, divide a predefined area on the screen into at least two subareas.

The terminal divides the predefined area on the screen into at least two subareas. With reference to FIG. 3B, the predefined area includes an area enclosed by a side 31 of the screen, two sides adjacent to the side 31 of the screen, and a third virtual side 32 parallel with the side 31 of the screen. The terminal divides the predefined area on the screen into 6*5=30 subareas.

Second, collect statistics on distribution density of the end positions of the sliding operations in each subarea, where the end positions are recorded in the successful triggering sample library.

The terminal collects statistics on distribution density of the end positions of the sliding operations in each subarea, where the end positions are recorded in the successful triggering sample library. The terminal collects statistics on distribution density of end positions in each subarea after recording an end position of a sliding operation that successfully triggers displaying of the side menu each time. In this embodiment, it is assumed that distribution density of end positions of sliding operations that successfully trigger displaying of the side menu several times is shown in the right figure of FIG. 3B.

Third, determine a subarea in which distribution density is lower than preset density as a false touch area.

The terminal determines the subarea in which the distribution density is lower than the preset density as the false touch area. Because a subarea with higher distribution density is an area in which end positions of habitual sliding operations of a user are located, a subarea in which distribution density is higher than the preset density is determined as a non-false touch area. Accordingly, a subarea in which distribution density is lower than the preset density is determined as a false touch area. As shown in FIG. 3B, an area indicated by oblique lines in the right figure is an updated false touch area.

After step 304 and step 305, the terminal adjusts the false touch area at the preset time interval according to the user habit, so that the false touch area is more precise, and probability of a misoperation is further reduced. In an actual application, initially set false touch areas of a same batch of terminals before factory delivery are generally the same; however, after the terminals are used by different users for a period of time, updated false touch areas are different due to different user habits of the different users. The terminals have a function of adjusting, after learning a user habit, a size and/or a location of a false touch area.

In addition, in this embodiment, recording the end position of the sliding operation that successfully triggers displaying of the side menu each time is only used as an example for description. The terminal may also determine the size and/or the location of the false touch area by recording a track of the sliding operation that successfully triggers displaying of the side menu each time. Displaying of the side menu is triggered only when the track of the sliding operation is not within the false touch area.

In conclusion, in the side menu displaying method provided in the embodiment, a sliding operation of sliding starting from a side of a screen is received, whether the sliding operation meets a predefined condition is detected, and a side menu corresponding to the side of the screen is displayed when a detection result is that the sliding operation meets the predefined condition. The predefined condition includes that a sliding speed of the sliding operation is greater than a preset threshold, and an end position of the sliding operation is not within a preset false touch area. This resolves the problem, existing in the other approaches, that a misoperation occurs because a notification bar is triggered and displayed unknown to a user, and achieves an effect that a side menu is triggered and displayed only when a sliding operation is a quick sliding operation and an end position of the sliding operation is not within a false touch area, thereby preventing a misoperation that occurs because the side menu is triggered and displayed unknown to a user.

In addition, the embodiment provides another specific manner of determining a false touch area, that is, updating the size and/or the location of the false touch area by recording the sliding operation that successfully triggers displaying of the side menu each time, so that the false touch area becomes more precise.

The memory 620 may mainly include a program storage area and a data storage area. The program storage area may store an operating system, an application program (such as a sound playing function or an image playing function) that is required by at least one function, and the like. The data storage area may store data (such as audio data or a phonebook) that is created according to use of the terminal 600, and the like. In addition, the memory 620 may include a high-speed random access memory, and may further include a non-volatile memory, for example, at least one disk storage device, a flash memory device, or another volatile solid-state storage device. Correspondingly, the memory 620 may further includes a storage controller, so as to provide the processor 680 and the inputting unit 630 with access to the memory 620.

The inputting unit 630 may be configured to receive input digital or character information, and produce signal input of a keyboard, a mouse, a joystick, or an optical or trackball signal, which are related to a user setting and function control. Preferably, the inputting unit 630 may include a touch-sensitive surface 631 and another input device 632.
